IMPROVEMENT IN TRUSSES.

ilg'r rgehlile raamt turtu these tetterrt zitent :mh making' pitt ni tp same.

To ALL WHoM IT MAY coNcEEN:

Be it known that'I, lSAMUEL GREEN, of the city, ccunty,` and State of New York,v have invented a new 'and `useful Improvement in Hernia-Truss pand I' d'o hereby declare` that the following is a full, clear, and exact description'thereof, which will enable others skilled in the art to make and use the same, reference being had' to the accompanying drawings, .forming lapart of this specification, in which- Figure 1 is a perspective view of` my improved truss.V

Figure 2 is-a detached view of a. pad and spring. Similar-letters of reference indicate corresponding parts'. This invention relates to an improvement the'construction of a truss forruptures of' the bowels, or hernia, and consists in a. novel and simple combination of springs and pds'with the main supporting-bars, as herein- 'after more particularly described.V vThis is'a cheap, eii`ective, and convenient truss, especially adapted to labor ing men.

to fit the back ofa patie'nt, 5n the ends of `v'vhich metal strips areattached straps b to pass around the person and be fastened with abucklevin the usual ivdy. Two curved steelsprings c c, of considerable power, are made fast at oneend to the under side of the centre-plate a, while the outer ed of' each spring bears'upon the under A A represent tw'osti metal strips, united by hinge-joints to a smallcentre-plate, a, and curved somewhat side of the metal stripsvA A, as shown in iig. 1. Two sti' metal plates B B'are secured to the centreplate a.

over the springs c c by set-screws d d, ,which pass through slots in their ends, allowing them to be lmoved for adjustment of the pads C C, which are attached to stiili` metal plates e e, that are liinged upon the endsof a crosshead, g, on the. outer end oi" each of the plates e e. Lightcurved springs 7L z are fastened at one end tothe cross-heads g y, while'the other end bears-upon each of the metal plates e `e, when theV pads C C are in place on the patient, and produce a, gentle pressure of Vthe pads upon the rupture;

It will be observed that when the truss is attached to4 the personl of a. patient, the main strain produced by any movement of the body willbe exerted directlyon the springs c c, by tliemain plates AA, while the pads C C will hear ligbtly'and evenly at all times upon the rupture, by means ofthe light springs la t, which :are entirely relieved from directstrain by the movement ot' the body, and thus the rupture will be'protected and guarded against anyundue pressure or derangement of the pads. n

Having described my invention, what I claim as new, and desire to `secure by Letters Patent, is-

The combination and arrangement of the main plates A A, hinged to the centre-plate a, the st iif'springs c c, the slotted adjustable plates B B With'crossfheads g, the pads C C, andthe light springs zs ubstantially as and for the purpose described.

The above specification of my inventionisigned by me, this y3'1st day of July, 1867.
